Kobe Bryant is in a court battle to try to keep his mother from auctioning off mementoes from his high school days in Pennsylvania and his early years with the Los Angeles Lakers.

A New Jersey auction house filed a lawsuit in U.S. District Court in Camden on Thursday for the right to sell the stuff after the NBA star's lawyers wrote the firm telling it to cancel a planned June auction.

The disagreement is a high-value, high-profile version of a question many families face: Can Mom get rid of the stuff a grown child left at home?

In this case, the 900 mementoes happen to be worth upward of $1.5 million.

Among the first 100 or so items Pamela Bryant intends to sell: the NBA star's jerseys, practice gear and sweatsuits from Lower Merion High School; varsity letters; a trophy for being the outstanding player at the 1995 Adidas ABCD basketball camp; and a signed basketball from the 2000 NBA championship game.

And then there are rings, for the 1996 Pennsylvania high school championship, a pair that the Lakers made for Bryant's parents for the 2000 NBA championship and one from the 1998 NBA All-Star game.

According to court filings, Pamela Bryant struck a deal in January with Goldin Auctions in Berlin, N.J., which earlier this year sold a rare Honus Wagner baseball card for a record $2.1 million.

She got $450,000 up front, which she intended to use for a new home in Nevada.

In its court filings, Goldin says Pamela Bryant told the auction house that she asked her son five years ago what he wanted to do with the items that were in her home.
